Title: Manufacture of semiconductor device
Inventor: MIYATAKE HIROSHI
IPC: H01L21/322
Filed: 1989-12-28
Abstract: PURPOSE:To improve the durability of gettering capacitance, to reduce adhesion to a wafer surface of Si and SiO2 particles from a rear and to enhance the controllability of the formation of a gettering source by capturing and removing the contaminative impurities of an active region in a semiconductor substrate to the rear of the substrate or a section near the rear by a plurality of trenches formed to the rear of the substrate. CONSTITUTION:Trenches 2 are manufactured by selectively executing etching to a rear 2 as a surface opposed to the device active region of a silicon wafer 1, and the strain field of a crystal is formed. Heavy metal impurities and Na impurities, etc., introduced by process con tamination are removed and captured from the device active region while using the strain field as a gettering source. Since crystal line strain due to the regularly formed trenches is employed as the gettering source, a semiconductor device is stabilized against a high- temperature process, and the crystalline strain is not shaped by the damage of the rear of a wafer, thus reducing the adhesion of particles onto a surface from the rear of the wafer, then preventing contamination due to particles. Accordingly, gettering capacitance having stable durability and high controllability is obtained.

Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic disc device with larger device life by restricting changes in the degree of lifting of a head with respect to variations in the length of a chamfer attributed to the working accuracy of a magnetic head chamfer part. SOLUTION: In the machining of a magnetic head chamfer 9, the angle 12 of chamfer is set in the range of 0.7 deg.-2 deg.. As a result, a negative pressure generated within a magnetic head slider is kept constant with respect to variations in the length 11 of the chamfer attributed to a machining accuracy of the chamfer part. This can restrict changes in the degree of lifting between heads and also enables supplying of a highly reliable magnetic disc device with longer device life.

IPC: B41J2/335
Filed: 1993-12-17
Abstract: PURPOSE:To provide a thermal head which can eliminate effectively and stably the charge of a wear-resistant film for protecting heat resistors without a complicated manufacturing process. CONSTITUTION:A conductive metal cover 40 for covering a part of a head substrate 11 and a driving IC 17 on a circuit substrate 12 is set in a manner in which a part (40a) of the cover is connected electrically in the state of being pressed elastically to a wear-resistant film 16 covering a plurality of heat resistors 13 arranged and disposed on the head substrate 11. As the electrically continued state between the conductive metal cover 40 and the wear-resistant film 16 can be stabilized at all times by grounding another part of the conductive metal cover 40, the charged state generated on the wear-resistant film can be eliminated always in a good manner to prevent the static destruction or the like of the heat development resistors. The above arrangement, therefore, can contribute to the improvement of reliability of a thermal head.

Filed: 1991-12-25
Abstract: PURPOSE:To enable control of an inverter element operating at a high speed, by minimizing a software processing time in generation of a PWM signal for driving the inverter element. CONSTITUTION:A timer 11 outputs a value which changes in the same way as a waveform stipulating a carrier wave of a PWM signal. A comparison register 12 controls the period of the timer 11.

Abstract: PURPOSE:To detect the presence of an adhering substance to the surface of a sample or the change of a material, etc., of the sample, and to correctly measure the surface state such as shape or the like of even a sample with much adhering substance, e.g. a biological sample, etc. CONSTITUTION:A probe 4 is set opposite to a sample 2. When the probe is brought close to or in touch with the sample 2, a physical amount acts between the probe 4 and sample 2, thereby bending a spring member 3 holding the probe 4.

A controller 7 receiving the shift of the bending amount and the change of the bending angle as inputs thereto comprises a control circuit for controlling a distance between the probe 4 and sample 2 and a fine adjustment mechanism. A fine adjustment stage 1 finely adjusts the sample 2 in X and Y directions to scan a measuring surface of the sample 2 to the probe 4. A display device 8 displays output of the bend detector 5 or controlling amount by the controller 7 with using the scan of the minute adjustment stage 1 as positional data of the surface of the sample 2, thereby displaying the physical amount, e.g. shape of the surface of the sample 2, friction force, etc.

The refractive index n1 of the fiber 12 and the grinding angle alpha1 of the ferrule 11 and the fiber 12 are so selected as to satisfy a relation (alpha2/alpha1)=(n2-n1)/(n2-1) therebetween. As a result, the optical axis of the ferrule 11 is made parallel with the optical axis direction of the fiber 12.

IPC: G11B21/21
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To stabilize a floating amount of a head slider and a resultant distance between a recording/reproducing element and a record medium by moving a pad in a vertical direction with respect to a floating surface and projecting the pad when in a still condition of the record medium or both in the still condition and at the start of the operation while, in a regular condition, reducing a projecting amount of the pad to a position at which a floating characteristic reaches a stable condition. SOLUTION: When a record medium 5 stops, a shape memory alloy actuator 4 is not energized so as to remain in a round shape. By projecting a contact pad 2 from a floating surface toward a record medium 5, the contact pad 2 contacts the recording medium 5 while the floating surface is prevented from contacting the record medium 5. Immediately before the start of operation of the record medium 5, the shape memory alloy actuator 4 is energized so as to deform into an elongated circle, so that the floating surface comes into contact with the resold medium 5. Thereafter, the record medium 5 is immediately started to operate. The power is continuously supplied to the shape memory alloy actuator 4 until the record medium 5 operates in a regular condition and the temperature becomes stable.

Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To raise Q value, self-resonance frequency, to make less susceptible to the effect from outside magnetic field at mounting time, and to raise heat- resistance temperature, by allowing a resin dielectrics to comprise, as a monomer, a high polymer material obtained by polymerizing a monomer composition containing fumaric diester. SOLUTION: A resin dielectrics is a fumarate-based polymer obtained by polymerizing a monomer composition containing, at least, fumaric diester as a monomer. The resin is used as an armor resin and a core for an inductance, while a band-like conductor coil is used. Here, relating to the fumarate-based polymer, a dielectric constant is 3 or less while a heat-resistance temperature is 270 deg.C or above. Thus, self-resonance frequency is raised to allow use in a high-frequency region, while a heat-resistance temperature is raised to allow use of such solder as of relatively high melting point.
